HARVESTE R.

SPECIFICATION forming part of Letters Patent No. 230,284, dated July 20,1880. Application filed May 8, 1880. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. J osLYN, of Rochester, in the county ofOlmsted and State of Minnesota, have invented certain new and usefulImprovements in Harvesters, of which the following is a specification.

My invention relates to improvements in apparatus for actuating thecutters and for inbricating the bearings of harvesters, and is shown asespecially adapted for application to mowers built by D. S. Morgan 8500., of Brockport, New York, under and in accordance with sundry LettersPatent 0f the United States, particularly the patent granted March 28,187 6, No. 175,511, for the invention of Wm. H. Seymour, and to whichpatent reference is hereby made for such full understanding of partswhich are not shown by the annexed drawings nor in detail described asmay be needful to a complete comprehension of my improvements.

My improvements will first fully be described in connection with theaccompanying drawings, preparatory to designating What is claimed.

Figure 1 is a view, partly in front elevation and partly in section, onthe line 1 1 of Fig. 3 Fig. 2, a similar view, the section being on theline 2 2 of Fig. 3; Fig. 3, a side elevation with thepitman in section;Fig. 4, an enlargedview, partly in plan and partly in section, on thelines 4 4 of Figs. 2 and 3, with the gearingframe plates or housingabout the crank-shaft omitted; and Fig. 5, a vertical section on theline 5 5 of Fig. 4.

As shown and described in the Patent No. 175,511, the main axle A issupported loosely by suitable wheels, the inner one being dished andinclosing an internally-toothed ring or spur-gear fast on the axleindependently of the wheel, so as to drive a spur-pinion on thecounter-shaft B, turning in bearings O 0 above and in rear of the axlein the arms or plates D D of the forked gearing-support or supplementaryframe outside the driving-wheel, and partially inclosed within its rimor flanged tread.

The counter-shaft carries a bevel-gear at E between the plates or forksD D of the gearframe, and drives a bevel-pinion, F, on an uprightcrank-shaft, G, turning in a sleeve-bearing, H, in thedownwardly-projecting portions I I of the frame-plates, which arescrewed or bolted together about the crank-shaft, the hearing for whichis formed halfin each plate.

To the extent above described the construction and operation of partsare similar to or essentially the same as in the Patent No. 175,511referred to.

T0 lubricate the various bearings I provide an oil-reservoir, J, with asuitable hinged lid and securing-catchfl. A strainer orperforateddiaphragm in the reservoir near its top serves to filter the lubricantas poured into it. A standard, K, detachably bolted to the top outerportion of the gearing-frame, supports the reservoir, and a tube issuingfrom the reservoir near its base is provided with a cock, L, andcommunicates with a system of oil-conducting tubes, M, M, N, O, and I".

When the cock is opened oil is admitted to the counter-shaft bearings OO by the pipes M M, and by the way of the pipes N and P and N and 0 oilpasses to the bearing Q, for the axle and to the crank-shaft G, which istubular and provided with several perforations to allow oil to escapefrom it toits long or sleeve bearing.

The tube 0 projects a short distance into the crank-shaft, and a portionof the oil passes down through this shaft to pitman-actuating apparatus,constructed and operating as follows: The tubular crank-shaft G isformed with or rigidly connected to an eccentric, R, dished or hollowedout at top, and provided with an upwardly-projecting stud, S, and with acentral opening, 1, through its bottom. The oil-passage through thecrank-shaft conducts the lubricant to the eccentric, and from thence itpasses by the opening 4 to the bottom of the socket or seat T, in whichthe eccentric turns. The periphery of the eccentric is conical, and acorresponding shape is given to the inner circumference or walls of theseat. The crankshaft has a shoulder, g, on it, fitting in ahole in asand-cap or disk-cover, U, for the eccentric. A screw, .9, passesthrough this cap into a low stud or post, S, on the eccentric. In thisway the cap is secured to the eccentric and crank-shaft and turns withthem, protecting the hollowed-out eccen tric from sand, trash, Ste.

A securing or clamping ring, W, of metal, rests at its inneredge upon orpartly overlaps the edge of the eccentric, and is secured to theeccentric-socket by several screws, w, which pass through one or moreelastic packing 'washers or rings, V, upon the socket T and outside theeccentric. The sand-cap and metallic securing-ring always occupy thesame relative positions, turning with the eccentric. The securing-ringand cap are drawn down snugly, but not too tightly, upon the eccentricedge.

The lubricant, which passes by way of the opening 1', spreads to thecontact-surfaces of the eccentric and its socket-bearing. Oil also flowsby a channel, it, to a socket for the conestuds a: a: of a split-ended0r forked pit-man, X, provided with a screw-bolt, Y, by which theyielding forks of the pitman are drawn into their seats and properlyheld in their bearin gs.

Wear is compensated by manipulating the screw-bolt Y, as will readily beunderstood.

The pitman connects with cutters in the usual way.

It will be seen that the conical eccentric can be adjusted in itsinclined or correspondinglyshaped hearing or seat to compensate wear bycompressing the ring washer or yielding packing, and that all the partsare thoroughly lubricated and protected.

A vent, 3 for the escape of air prevents any obstruction to the flow ofthe lubricant. This opening y serves also as an inlet by which to supplyoil directly to the eccentric when it is desirable to do so.

I am aware that lubricatirig-reservoirs have heretofore frequently beenemployed in various ways in connection with pipes leading to differentbearings to be oiled, and do not broadly claim supplying a number ofbearings from a single oil-supply by conducting-pipes. Neither do Iclaim, broadly, driving the cutters of a harvester by an eccentric and asocket or strap fitting around it, nor every way of Inbricatingcutter-driving mechanism of such type.

I claim as of my own invention 1. The combination of the tubularcrankshaft, the dished eccentric with which the oilpassage through thecrank-shaft communicates, the socket seat or hearing for the eccentric,the pitnian, and the cone-stud bearings supplied with oil from theeccentric-bearing, substantially as and for the purpose hereinbefore setforth.

2.. The combination of the crank-shaft, the dished or hollowed-outeccentric, its seat or socket, the sand cap or cover, the packingring,and the metallic securing-ring, substantially as and for the purposehereinbefore set forth.

3. The combination, substantially as hereinbefore set forth, of thecrank-shaft, the cc centric, the eccentric hearing or socket, thesand-cap having the vent therein, the secur ing-ring, and the packing,for the purpose described.

In testimony whereotl have hereunto sub scribed my name.
